BOT-TLE AND STOPPER.

SPECIFICATION forming part of Letters Patent No. 239,015, dated March 22, 1881.

Application filed April 23, 1880.

To all whom it may concern Be it known that I, HENRY. BARRETT, of

1 Hampton, in the county of Middlesex, England, have invented certain new and useful Improvements in Bottles and Stoppers, (for which I have obtained a patent in Great Britain,No. 3,935, bearingdate September30, 1879,) of which the following is a specification.

This invention relates to the improvements hereinafter described, and represented in the accompanying drawings, in internal disk-stoppers for bottles for containing aerated or gaseous liquids, (applicable also for bottles containing beer and other malt liquors also, in the bottles closed by such stoppers.

My improvements relate to a novel construction of bottle and of internal stopper to be used therewith, whereby I am enabled to em ploy a stopper of hard non-elastic material of larger diameter than the opening of the mouth of the bottle, and to introduce such stopper into and remove it from the interior of the bottle as required.

In thedrawings,-Figure 2 is a section of a bottle constructed. according to this part of my invention; Fig. 3,similar view, showing the stopper applied thereto; Fig. 1, plan of the mouth of the bottle.

In carrying out this part of my invention the stopper is formed of a circular disk, 70, as shown in plan and side views at Figs. 4 and 5, of suitable hard material, such as pearl, ivory, or glass, but preferably pearl, two of the sides of the said disk being in some cases cut or formed straight, as shownin Fig. 6, so as to give the stopper somewhat of an elliptical shape. The bottle, A, to be used with this stopper is formed, as shown at Fig. 2, with an interior shoulder in the neck, with ah annular groove,

m, in the shoulder, a slot or groove, 1, being formed vertically through the said annular grooved shoulder 011 each side. The diameter of the interior of the neck of the bottle below the shoulder is slightly in excess of the diameter of the hereinbefore described disk k, forming the stopper, (or of the larger diameter when the stopper is formed of the shape shown in Fig. 6,) whilethediameter of the stopper is slightly less than the diameter of the neck of the bottle between the bottom of the two hereinbeforerdescribed grooves Z. From this con- (No model.) Patented in England September 30, 1879.

struction it will be evident that if the stopper k be taken edgewise in a vertical direction it can be passed into the interior of the bottle through the hereinbefore-described slots or,55

grooves Z, the width of the slots 1 being slightly greater than the thickness of the stopper k. The stopper 70 having been introduced into the bottle, I then place in the annular groove m the seating for the stopper to bear against.

This seating I have found it advantageous to make of a suitable hard material-such as ivory, bone, vulcauite, or glass-a thin ring of compressed cork being combined with or cemented to each side of the hard ring, the circumference of thesaid seating being of the same shape as that of the hereinbefore-described stopper, (shown in Fig. 6,) so that it may l)epassed into the bottle through the hereinbefore-described slots 1 l, and is then placed (by means of a suitable tool) into the annular groove m and cemented in position, care being taken that the shorter diameter of the ring is placed transversely to the slots 1 l in the annular groove. tain a yielding seat for the stopper k to bear against, and also a yielding seat to form an air-tight joint between the ring and the bottle.

It will be understood that in place of the compound elastic seating, such asis above referred to, a simple seating, such as that made of vulcanized india-rubber, may be used as a seating with my improved disk-stopper.

Instead of the bottle being formed with the slots Z Z, as hereinbefore described, the diskonto its seat, the neck of the bottle serving as 5 a guide. l.

Instead of using my improved flat or disk stopper separately from its elastic seating, I find that they may be advantageously used in permanent combination, forming a compound I00 stopper and seating. One form of this modification of my improved stopper and seating is By these means 1 0b- 75 A bottle provided with the shown in plan and section at Figs. 7 and 8 of the accompanying drawings. This stopper is constructed of a ring of vulcanized india-rubher, a, formed with a groove or slit around its interior, in which is placed a disk, I), of glass or other suitable material. The disk I) is preferably made somewhat elliptical, as shown by the dotted lines, Fig. 7, to allow of the stopper being more easily forced through the neck of the bottle. A great advantage of this construction of stopper is, that no elastic seating is required in the neck of the bottle, which requires to be formed with merely a shoulder for the elastic ring a to bear against.

An important advantage arising from the employment of the hereinbefore-described flat stoppers is, that the stopper does not roll to the mouth of the bottle while the contents are being discharged; or, should it do so, it will rest edgewise, and will therefore not interfere with the discharge of the liquid, as is so often the case with internal stoppers as at present constructed.

I sometimes employ a disk of vulcanite or like material, which, being heated, may be rolled so as to allow of introducing it into the bottle. It is then strengthened in any suitablemanner, and will then recover its normal or flat shape; or, if abrittle material be used, it must be afterward strengthened and flattened out into its normal position.

It will be understood that when a stopper of a non-yielding material is employed the bottle must be furnished with an elastic seating for the stopper to bear against.

Having thus described the nature of my said invention and the best means with which I am acquainted for carrying the same into effect, I would have it understood that I do not confine myself to the precise details herein laid down and shown in the accompanying drawings, as the same may be varied without departing from the peculiar character of my invention; but

What I claim is- 1. In combination with a bottle having a circular month, an internal stopper ofrigid material in the form of a disk, as described, having a diameter greater than the diameter of the circular mouth, and adapted to be inserted edgewise into the mouth of the bottle.

2. The combination, with an'internal diskstopper, of a bottle formed with an annular grooved shoulder for receiving the seating, and with vertical slots to allow of the introduction of the disk-shaped stopper, as hereinbefore described, and representedin Figs. 1, 2, 3 of the accompanying drawings.

3. Theimprovedinternalbottle-stopperforming a combined disk-stopper and seating, consisting of a ring of vulcanized india-rubber surrounding a disk of suitable hard material, as hereinbefore described, and represented in Figs. 7 and 8 of the accompanying drawings.
